The measured resolution R=33529 and the dispersion 0.0635 A/pixel match up pretty well with the SimSpec for the MiniSHG.
Hi Ken,

The peak transmission is an interesting result. I wonder if the bandwidth is to spec. In trying to deduce this from the graph, I'd be curious to know the vertical scale and starting point/zero. Thanks for sharing your work - very interesting Ken
